Problems solved by technology

However, for the case of large bone loss, the thickness of the usual planar titanium mesh is relatively thin, and it often lacks sufficient strength after shaping, so it is difficult to become a qualified bone scaffold structure; if the thickness of the planar titanium mesh is too thick, it will not only lead to It is difficult to shape, and it will also produce an overweight foreign body sensation, and hinder the self-growth and repair function of the human body's own soft tissue or bone tissue

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings (FIG. 1-FIG. 6).

[0038] Fig. 1 is a schematic diagram of the structure of the three-dimensional mesh bone filler of the present invention. As shown in FIG. 1 , the three-dimensional mesh bone filler includes a three-dimensional structure, and honeycomb cavities are distributed along all surfaces of the three-dimensional structure. The honeycomb cavities are arranged in a regular grid. The regular grid 2 is a square array constructed by the cylindrical sides 1, obviously, it can also be a rectangular array, a triangular array, a rhombus array or a hexagonal array, or other irregular polygonal shapes. A regular grid can also be a circular array or an elliptical array.

[0039] The three-dimensional structure is a metal titanium product or a titanium alloy product. Of course, the three-dimensional structure can use other biological structural materials that me...

Abstract

The invention provides a bone filling material of three-dimensional grid structure and a preparation method thereof. The material is characterized in that the material comprises a three-dimensional structure body and alveolate cavities are distributed at all the surfaces of the three-dimensional structure body. The alveolate cavities are in regular grid arrangement and the regular grid is of square array, rectangular array, triangular array, rhombic array or hexagonal array constructed by cylindrical boundaries. The bone filling material is suitable for mixed repair of bone injury.

Description

technical field [0001] The invention relates to bone repair technology, in particular to a three-dimensional mesh-shaped bone filler and a manufacturing method thereof, which are used as a filling structure implanted in bone missing parts. Background technique [0002] At present, in surgical bone repair, such as the repair of craniomaxillofacial bone, trunk bone, upper limb bone, lower limb bone, etc., it is necessary to use implant materials, which are implanted into the missing bone as a bone substitute. Considering the requirements of biocompatibility and long-term implantation without rejection in the body, titanium is one of the earliest implant materials suitable for clinical use. However, for the case of large bone loss, the thickness of the usual planar titanium mesh is thin, and it often lacks sufficient strength after shaping, so it is difficult to become a qualified bone scaffold structure; if the thickness of the planar titanium mesh is too thick, it will not on...
